23 April 2026·Uptrue Team

⚙️ Dev Tools & CI/CD Weekly Comparison

Atlassian and Cloudflare Workers both demonstrated exceptional reliability during the monitoring period of 20–26 April 2026. Atlassian achieved 100% uptime with zero incidents, while Cloudflare Workers maintained 99.87% uptime, also reporting zero incidents across their monitored services.

TL;DR

Atlassian recorded perfect 100% uptime; Cloudflare Workers achieved 99.87% uptime
Cloudflare Workers delivered faster average response times at 139ms vs. Atlassian's 174ms
Both providers reported zero incidents and zero minutes of downtime during the monitoring period
Response time difference of 35ms favours Cloudflare Workers for latency-sensitive operations

Uptime This Week

Atlassian's 100% uptime represents flawless availability throughout the week. Cloudflare Workers' 99.87% uptime translates to approximately 11 minutes of unavailability across seven days. For mission-critical CI/CD pipelines, Atlassian edges ahead on availability, though both figures exceed enterprise SLA thresholds.

Response Time

Cloudflare Workers responded 35ms faster on average (139ms vs. 174ms), a meaningful difference for time-sensitive deployments and real-time integrations. Both providers maintained sub-200ms response times, suitable for production workloads, though Cloudflare's performance provides a measurable advantage for latency-conscious teams.

Incidents & Downtime

Neither provider experienced recorded incidents or downtime during the monitoring window. This zero-incident performance across both services indicates stable infrastructure for the Dev Tools & CI/CD category, though the small sample period should be noted when making long-term reliability assessments.

Historical Context

CI/CD and developer tools platforms have consistently tightened reliability standards over the past 18 months, with 99.9%+ uptime becoming the expected baseline rather than a competitive differentiator.

Which Should You Choose?

Choose Atlassian for absolute availability requirements and established enterprise CI/CD workflows; select Cloudflare Workers for latency-sensitive operations and edge-case performance optimization. Both are suitable for production use, with the decision hinging on specific architectural needs rather than reliability gaps.

About This Data
All uptime, response time, and incident data is collected by Uptrue's independent monitoring infrastructure. HTTP checks run every 5 minutes. An incident is recorded only after 2+ consecutive failed checks. Uptrue is not affiliated with any monitored service. For corrections: reports@uptrue.io

Frequently Asked Questions

Which provider is more reliable?

Atlassian demonstrated marginally higher reliability with 100% uptime versus Cloudflare Workers' 99.87%. However, both exceeded enterprise thresholds, and the 0.13 percentage-point difference represents approximately 11 minutes over seven days. Provider choice should prioritize your specific latency and integration requirements over this narrow uptime gap.

How often does Cloudflare Workers experience downtime?

During this monitoring period, Cloudflare Workers reported zero incidents and zero minutes of downtime. The 99.87% uptime figure reflects aggregate performance metrics rather than a discrete outage event. Long-term trend analysis across multiple weeks is recommended for predicting future downtime frequency.

How is this data collected?

All metrics originate from Uptrue's independent uptime monitoring infrastructure, which continuously probes provider endpoints and measures response latency. Data is gathered via external monitoring rather than relying on provider-reported figures, ensuring unbiased third-party assessment of actual service availability and performance.
